Generalised form of a three-digit number xyz is
(a) x + y + z (b) 100x + 10y + z
(c) 100z + 10y + x (d) 100y + 10x + z
Ajita starts off from home at 07.00 hours with her father on a scooter
that goes at a uniform speed of 30 km/h and drops her at her school
after half an hour. She stays in the school till 13.30 hours and takes
an auto rickshaw to return home. The rickshaw has a uniform speed
of 10 km/h. Draw the graph for the above situation and also determine
the distance of Ajita’s school from her house.
Extend the line segment on both sides to meet the coordinate axes.
What are the coordinates of the points where this line meets the
x -axis and the y-axis?
Locate the points P (3,4), Q (1,0), R (0,4), S (4,1) on a graph sheet
and write the coordinates of the point of intersection of line segments
PQ and RS.
Locate the points A(1,2), B (3,4) and C (5,2) on a graph sheet taking
suitable axes. Write the coordinates of the fourth point D to complete
the rhombus ABCD. Measure the diagonals of this rhombus and
find whether they are equal or not.
Locate the points A (1,2), B (4,2) and C (1,4) on a graph sheet taking
suitable axes. Write the coordinates of the fourth point D to complete
the rectangle ABCD.
Plot a line graph for the variables p and q where p is two times q i.e,
the equation is p = 2q. Then find.
(a) the value of p when q = 3
(b) the value of q when p = 8
Draw a graph for the radius and circumference of circle using a
